grep: fix hash(linestate) to not include linenum
linestate.__eq__() just compares the line values whereas __hash__() does
hash both self.line and self.linenum, which violates the rule. __hash__()
was added at fb502719c75c, "python 2.6 compatibility: add __hash__ to
classes that have __eq__" with no additional remarks, so this would probably
be a simple mistake.
The test output changed because difflib.SequenceMatcher() internally uses
a dict. As you can see, the line "export" is unchanged at the revision 2,
so the new output is correct.
